The force of buoyancy exerted by the atmosphere on a balloon is B in the upward direction and remains constant. The force of air resistance on the balloon acts opposite to the direction of velocity and is proportional to it. The balloon carries a mass M and is found to fall down near the earth’s surface with a constant velocity . How much mass should be removed from the balloon so that it may rise with a constant velocity u?

Motion in Two Dimension – Projectile Motion for JEE-NEET-01

JEE Physics Notes: Projectile Motion JEE Physics Notes Motion in Two Dimension: Projectile Motion 1. Introduction to Projectile Motion The motion of an object is called two-dimensional if two of the three coordinates required to specify the position of the object in space change with respect to time. In such a motion, the object moves
